.A colleague has questioned the choice of DMA channel 1 for the tape
.drive, to which I replied that the tape driver was installed by the
.mkdev tape `auto-configure' option (leaving all parameters as zero).
.
.Has anyone experienced problems using DMA channel 1 for a tape drive ?
.
.Has anyone had problems with the `auto' option of mkdev tape ?
.
.Might choice of DMA channel have any effect on the previously mentioned
.kernel panics?

Yes - I am trying to get a Colorado Memory Systems 40 meg tape drive
to work with my system (386 AT, SCO Xenix 2.3.2) and cannot get the 
system to recognize it. I've tried every option available with the
mkdev tape command and still nothing. The tape drive isn't connected through
the floppy controller - it has its own controller board.
